Rotary Potentiometers, Rheostats, or variable resistances are electrical components that have been in use for a long time. They are able to adjust the amount of electrical resistance in a circuit, making them useful for a variety of applications. One such device is the 3547H-1AC-103B. This article will discuss the application fields and working principle of this particular device.

The 3547H-1AC-103B is a rotary type potentiometer that is used to adjust the resistance in a circuit. Its main application is as an adjusting element or control device to adjust the current flowing through the circuit. It is also used as a voltage- or current-dividing element in power supplies, servo systems, and other applications requiring a variable resistive load. It is a three-terminal device, with one terminal connected to ground, another connected to a voltage source, and the third, the wiper (or slider), connected to either the ground or voltage source.

The working principle of the 3547H-1AC-103B is simple. When the wiper is moved along the resistor element, it changes its resistance. This change in resistance is proportional to the displacement of the wiper along the surface of the resistor element. As the wiper is moved along the surface of the resistor element, the electrical current changes accordingly. Depending on the resistance value of the resistor element, the resulting current will either increase or decrease.

Another important application field of the 3547H-1AC-103B is as a voltage controlled resistance. This occurs when the voltage source (such as a battery) is connected to one end of the device and the wiper is set to different positions. By changing the voltage applied to the wiper, the current flowing through the circuit can be adjusted accordingly. The voltage applied to the wiper should not exceed the ratings recommended by the manufacturer. Overloading the resistor element can cause a permanent damage to the device.

Finally, the 3547H-1AC-103B can also be used as a current controlled resistance. Depending on the current supplied to the wiper, the resistance of the resistor element will increase or decrease. This offers an adjustable current flow in the circuit so that it can be adjusted to the desired value. In this type of application, the current supplied to the wiper must not exceed the current ratings of the component.

In conclusion, the 3547H-1AC-103B rotary potentiometer is a useful device with a wide range of applications. It can be used as an adjusting element or control device, a voltage or current-dividing element, or a voltage or current-controlled resistance. Moreover, the working principle of this device is simple and straightforward. With these qualities, the 3547H-1AC-103B is an essential part of any electrical system.
